plication August 30,

6 Claims.

This invention relates to, and has for its 0 ject the provision of,anion mercuri 1,3-dihydroxy 4-alkyl 6-halo benzene.

This application is a division of Serial No. 743,840, filed September13, 1934, now Patent No. 2,137,236.

The mercuri alkyl phenol derivatives of this invention have the generalformula Halogen- Anion-Hg Acetoxymercuri 1,3-dz'hydroary 4-lrutyl6-chloro benzene c1130 0 o Hg- 0.9 g. 1,3-dihydroxy 4-butyl 6-chlorobenzene is dissolved in 10 cc, ethyl alcohol, and while the solution isrefluxed, 1.5 g. mercuric acetate dissolved in 10 cc. water is added.After two hours of refluxing, a test for divalent mercury beingnegative, and the reaction mixture being brownish and turbid, thealcohol is evaporated off and the mass dissolved in dilute alkali.Finely divided reduced mercury is filtered out. Precipitation iseffected by means of acetic acid. For purification, the precipitate isdissolved in boiling alcohol, and a slight residue filtered out.Diluting. the alcoholic solution with water yields the desired compoundas a pinkish precipitate.
